Mark Miller

Mark Miller is the Director of Environment and Natural Resources Litigation at Pacific Legal Foundation, where he leads the firm’s efforts to protect individuals and small businesses from government overreach in matters involving land, water, and natural resources.  

Mark first joined PLF in 2014. A seasoned appellate specialist, Mark has litigated several high-profile cases for PLF, including Weyerhaeuser v. United States Fish & Wildlife Service, U.S. Army Corps of Engineers v. Hawkes Co., and United States v. Robertson, all of them unanimous Supreme Court of the United States wins for property owners fighting federal overreach via the Clean Water Act and Endangered Species Act. 

In 2020, Mark left PLF to serve as General Counsel and later Chief of Staff for then-South-Dakota Governor Kristi Noem. As Noem’s longest-serving chief of staff, he worked behind the scenes to advance limited government, cut red tape, defend individual rights, and promote free-market principles. In 2023, he returned home to PLF. 

A frequent commentator and public speaker, Mark regularly appears in print, on radio and TV, and before legislative committees across the country. His commentary and work has been featured in The Wall Street Journal, CBS News, The View, CBN, and Fox News. He is a regular guest on SiriusXM’s POTUS channel, offering insight on Supreme Court cases and trends. 

Mark earned both his undergraduate and law degrees with honors from the University of Florida. He clerked for U.S. District Judge Henry Lee Adams, Jr., and Florida state appellate Judge Emerson R. Thompson, Jr.—two mentors who deepened his commitment to the Bill of Rights, especially the Fourth, Fifth, and Fourteenth Amendments. 

Mark serves on the Board of Trustees for the University of Florida College of Law, his alma mater, and he is a member of the boards of directors for both Americans United for Life and Farm of the Child USA, the latter a nonprofit that supports an orphanage and school for children in need in Honduras called La Finca del Niño. 

He and his wife Mindy, a Catholic school principal, have four children—two graduates of the University of Florida like their father and two the University of Notre Dame like their mother. On fall weekends, you’ll find Mark rooting for either the Gators in the Swamp or the Fightin’ Irish in the House that Rockne and Holtz Built. 

Mark is admitted to practice law in Florida and New Jersey.
